I wish I could help. I stuttered for 65years and recovered through psychological therapy dealing with my abusive childhood. I can recommend two youtube sites though. Both doctors are named Maguire and McGuire. Each has different methods. The first one, Maguire is at: YouTube ‘Dr. Gerald Maguire’ He's a psychiatrist who uses medication. I know a patient who is NOW 99% fluent. The other Dr.McGuire’s program is used in the UK and other countries and ill send a link to an interesting video. YouTube ‘McGuire stuttering’ YouTube also: Stammer School: https://youtu. be/bNkOeIBKZNs Keep in touch and good luck, Sue
